Municipal solid waste as an energy resource: Mass-burn incineration or small-scale pyrolysis?
No full textThe issue of using municipal solid waste (MSW) as an energy source was presented and attempted to identify a more sustainable technology for energy recovery. The two technologies were evaluated and compared on a life cycle basis, using Life Cycle Assessment as a tool. Among other factors, the choice of a more sustainable technology depended on the motivation for using the technology, i.e., the service provided. If, for example, the main aim is to reduce the amount of solid waste reaching landfills and to comply with the EU Landfill Directive, then large-scale incineration was a more environmentally sustainable technology overall. If on the other hand, the aim is to recover energy from waste, a small-scale pyrolysis/gasification process was a better option. Understanding of both life cycle considerations and local conditions was essential in choosing the "appropriate technology". This is an abstract of a paper presented at the 7th World Congress of Chemical Engineering (Glasgow, Scotland 7/10-14/2005)

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
